Canopy Roof Soft Washing
Imperial Golf Estates

Imperial Golf Estates is a gated community off US-41 in North Naples 34110, with its club at 1808 Imperial Golf Course Boulevard. The club opened in 1969 on about 300 acres of wooded, rolling land with spring-fed lakes.

Two 18-hole courses run through it: the East, an Arthur Hills design of 7,008 yards, and the West by Ward Northrup, with sharp doglegs and water. The homes back onto those fairways and lakes under the trees the lead describes.

Pines and live oaks drop needles, leaves and seed pods all year. They pile up in valleys, behind chimneys and in gutters, where they hold water against the roof and break down into a dark stain.

Lots here are large; one Noble Court listing describes a lot of nearly half an acre, and Princess Court has oversize lots. A big lot usually means a large, multi-plane roof with valleys and hips, which is where debris collects first.

The canopy also keeps roofs in shade for most of the day. A shaded roof dries slowly after dew and rain, and slow-drying roofs grow algae and lichen far faster than roofs in open sun. On many Imperial lots, the shaded slopes streak while the sunny ones still look fine.

The dark streaking is mostly a cyanobacterium, Gloeocapsa magma. The Asphalt Roofing Manufacturers Association calls it probably the most common of several algae species behind roof discoloration and says it is most widespread in the Gulf States, where warm, humid weather favors it.

Owens Corning, a shingle maker, says the organism is carried through the air and settles on roofs, and that green algae and moss are different species. It also says it has not seen evidence that algae deposits affect shingle performance, so on a shingle roof the streaking is a matter of appearance.

Imperial’s homes are set on large lots around two golf courses, and many have tile roofs, while others have shingle. Both need the same gentle approach: clear the debris by hand, then soft wash so nothing is blasted loose or cracked.

Imperial is mostly single-family homes, with condos, coach and carriage homes and attached villas in the mix. We confirm the roof material on each home at the walk-through rather than assume, because tile and shingle are cleaned under different manufacturer guidance.

For shingles, ARMA recommends household bleach and water, mixed to the shingle maker’s directions, left on for at least 15 and no more than 20 minutes, then rinsed with a gentle spray. It warns against a power washer, brushes and brooms, and Owens Corning adds that high pressure and scrubbing loosen granules and shorten roof life.

Concrete tile is different. Eagle Roofing Products, a concrete tile maker, recommends water only for routine cleaning, at no more than 1,200 psi, and says higher pressure can affect the tile’s pH and discolor it. We stay well under that limit.

For a heavily soiled tile roof, Eagle allows a cleaner in the most diluted solution possible, and only one compatible with concrete, since some products can change the tile’s pH or etch the surface. Our mix is chosen with that in mind and kept no stronger than the roof needs.

A cleaned roof is slippery, and Eagle calls walking on wet tile difficult and dangerous. Our crew works with fall protection, keeps its feet on sound tile, and does not walk the eaves.

Because the canopy never stops dropping, a cleaning schedule beats waiting for streaks. Shaded roofs here tend to streak again first, so we book by condition rather than calendar, with gutters checked every visit.

ARMA is plain that roof cleaning is temporary and the discoloration can return. Under Imperial’s canopy, where needles keep landing and slopes stay damp, the recurring schedule above is what keeps a roof looking clean.

If you replace a shingle roof later, Owens Corning notes that algae-resistant shingles carry metals such as copper in their granules. It is worth asking your roofer about if your lot is heavily shaded.

Before we start, every slope is photographed and any cracked or slipped tile is noted. Eagle recommends routine inspection for cracked tile and drainage problems, and our photos give you a record of what was there before the cleaning.

Gutters are flushed after the roof is treated, so anything loosened during the clean does not sit in the trough. On lakefront lots such as those on Empress Court, we direct rinse water onto the lawn rather than toward the lake.

Prices start at $299 for a single-story roof, $399 for two stories and $499 for a large estate or complex roof. Tile with mortared ridge caps starts at $349, and a roof with a house wash at $599.

We are pre-registered at the Imperial gate, licensed and insured, and send photos with a written record after each visit. Call 239-544-1165 to book, and ask about the driveway under the same trees.
